The parameters of secondary air fan in 300MW circulating fluidized bed(CFB)boilers are close to that of the primary air fan in 600MW pulverized coal(PC)fired boilers.Thus
suggestion that the secondary air fan in 300MW CFB boilers can be two-stage dynamic adjustable axial flow fan was proposed.Compared with such schemes as centrifugal fan with frequency conversion or centrifugal fan with damp
the two-stage dynamic adjustable axial flow fan has wider regulation range and higher adjustment efficiency.Moreover
it occupies smaller area
thus has lower initial investment and maintenance cost.Therefore
it is more reasonable to adopt two-stage dynamic adjustable axial flow fan as the secondary air fan in 300MW CFB boilers.
